Be it lmown that I7 MARQUES IVIEPCKE,

a citizen of Brazil, and a resident of thel which act as means forspacing the ceiling elevating screw embodying certain features t fromadjacent structures. i

A still further obv'ect is the method of setting up a support and thencasting a ceiling 'on the support in such a manner that certain parts ofthe ceiling will be connected with the floor members of the building. l

In the accompanying drawings- Figure 1 is a longitudinal verticalsection through part of a room disclosing a ceiling and supportingscaffolding embodying the invention.

Figure 2 is a sectional view through Figure 1 approximately on line 2-2.

Figure 3 is a detail perspective view of an of the invention.

F igure 4 is a broken away top plan view4 of a ceiling showing part ofthe scaffolding and how the matter is applied thereto.

Figure 5 is a perspective view of a number of iioor joists andreinforcing elements connected therewith. n

Figure 6 is a fragmentary sectional view showing a cornice and part ofthe ceiling, the same embodying certain features of the invention.

Figure 7 is a view similar to Figure 2 but showing how ornamental centerand side pieces may be connected with the ceiling.

Referring to the accompanying drawings by numeral, 1 indicates a floorof a. room and 2 one of the walls thereof while 3 indicates the joistsof the floor above. In the present invention it isy aimed to place theceilings in position for each room before the ooring 4 has been placedin position though after the joists 3 are properly arranged. In

carrying out this idea according to they present Yinvention a number ofdepending plates or strips 5 are secured to the respective joists 3 bynails or otherwise, so' that the apertures therein will be in the samehori- Zonta] plane. lires 6 are positioned to extend through the variousplates 5 as shown in Figure 5 andthen' transverse wires 7 are laid'tliereover-for forming a rather 4open net work which is to act as metalreinforcementfor the ceiling. Preferably in providing this net work ofwires the various plates 5 are threaded' over certainof the wires andthen secured in place, 'after which some transverse and somelongitudinal wires are positioned as shown in Figure 5 and se- `cured byany desired number of tie wires5. f

In the drawing a tie wire has been shown at each crossing of the `wiresbut this is ordinarily not necessary as an occasional tie wire will'answer the purpose.

I-Iowevenbefore the'net work of wire has been placed in position asshown in Figure "5, a scaffolding is arranged on floor 1. as

shown in Figure 1. This scaffolding consists of any suitable number ofsupporting uprights 8 provided with bores 9 for receiving the ends ofthe respective lifting screws 10. Each of these screws is provided witha wing nut 11 whereby the screw may be moved upwardly or downwardly.Each of these screws is provided witha plate 12 on which a vchannel iron13 is placed. On the various channel irons 13 transverse additionalirons 14 are positioned, the channelv irons 14 being of sufficientnumber to provide a proper lfoundation for the various bars 15 which arepreferably wood and square in cross section. The bars 15 as shownv inFigures 1 and 4 presentan even lfoundation onl which one or morel stripsof' linoleum 16 are placed or some other suitable sheet material whichwill present a smooth upper surface and which will lie liatwise againstthe bars 15. After the linoleum 16 has been placed in position the wirenet work as shown in Figure 5 is then provided as above described andwhen this has been properly provided, both the scaffolding andreinforcement are ready for the .pouring action. A suitable finishingcoat of plaster Paris or other materiall is then poured onto thelinoleum and allowed to spread out under the action of gravity. Ifdesired, this spreading action may be assisted bv a trowel or otherinstrument. When this layer has been properly placed in position abacking `correspondingly positioned.

layer 18 is poured, said backing layer merging into the layer 17 andsubmerging the wire mesh reinforcement as indicated in Figure 1 thoughpreferably not extending to the lower surface of the joists 3. In thisway the layers 17 and 18 are supported by the wire mesh which in turn issupported by the strips or plates 5 connected to the joists 3. Aafterthe layer 18 has been properly poured and distributed, if necessary theentire structure is left standing as shown in Figure 1 until theselayers have properly set, after which, the scaffolding is removedincluding the layer of linoleum whereupon a smooth finished surface ispresented.

ln case the room is very large a number of blocks or strips of linoleumis used and usually there is a slight flange or bead formed betweenthese strips of 'linoleum which must be cut off by a trowel or otherinstrument after the linoleum has been re moved. The aggregate forminglayer 18 may be made with a composition including hair of any desiredkind or in fact may be made of any suitable composition or vmixture andWhen properly cast will present an extremely strong ceiling which willsupport the weight of workmen if necessary.

Sometimes it may be desirable to provide a cornice for a room and whenthis is the case a cornice fitting 19 is provided as shown in Figure 6which is clamped to one of the posts 8 or to some other part of' thescaffolding by any suitable form of clamp 20. The

plates 5 adjacent the corners 9 are made longer to'substantially conformto the shape of the corners and the reinforcing wires are Also, if desired, ornamentation may be made in the center of the room or a shortdistance from the side walls as indicated in Figure 7. In constructingthe ceiling as shown in Figure 7 the ornamental member 21 is arranged inposition and supported on the scaolding below the wire mesh before anyof the layers of plaster material have been placed in position. The sideornament 22 is' also placed in position and supported by the scaffoldingthough preferably the linoleum 16 is cutaway for accommodating theornamentation 21 as well as the ornamentation 22 and the ornaments areusually supported entirely or somewhat by the linoleum. The casting thenis made in the manner above described and by reason of the adhesivequalities of the layer 17 it will readily ad here to the ornamentalmembers 21,and 22 so as to thoroughly support the same and in turn besupported by the layer 18. l

After the two layers 17 and 18 have been deposited and allowed to set,either with or without the cornice 19 or the ornaments 21 and 22, thescaffolding is removed carefully and the linoleum 16 is finally removedcarefully which may be readily done as it will usually peel ofi' whenthe layer 17 has set. rlllhis is possible because the linoleum is smoothon the upper surface and consequently the layer 17 will not readilyadhere thereto.

This construction of ceiling is very strong and also provides an airspace below the joists and above the ceiling. This air space isimportant for many reasons, as for instance, it consists in preventingthe spread of fire and provides a dead air space which will make asound-proof construction very desirable in apartment houses andelsewhere. 1n Figure 1 of the drawing only a small space `below thejoists has been shown but it will be evident that this space may belarge or small as desired.

' lVhat l claim is':-

ln a ceiling of the class described, a plurality of hangers eachconsisting of a strip of metal, means connecting said hangers to asupport, a reticulate suspended from said hangers, said reticulateconsisting of a plurality of wires each extending parallel to the otherand through a series of said hangersl and a plurality of wires eX-tending across and secured to said'first mentioned wires, a plastic bodyembedding said reticulate, and an ornamental finish on the under surfaceof said plastic body.
